Let an agent explain the chemistry sense of suspension, relay properties, examples and uses from chemistry sources, describe the named examples, and distinguish a suspension from a solution, a colloid, an emulsion and other senses of suspension.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the chemistry sense of suspension, relay properties, examples and uses from chemistry sources, describe the named examples, and distinguish a suspension from a solution, a colloid, an emulsion and other senses of suspension.

In chemistry, a suspension is a heterogeneous mixture in which solid particles are dispersed through a fluid but are large enough to settle out over time and to be filtered, unlike a solution or a colloid, with examples the registry aliases name such as cell suspensions, milk of lime, slurry ice, moonmilk, electrorheological fluids that stiffen under an electric field and moonmilk; suspensions must often be shaken before use, as in some medicines and paints. This chemical sense differs from suspension as a vehicle system, as a temporary halt and as hanging.

What it is for: A mixture of settling particles in a fluid.

It can be explain properties; relay examples and uses; describe named examples; distinguish related mixtures and senses.

Distinguishing features

Heterogeneous

Particles settle

Filterable

Often needs shaking

What it looks like

A cloudy fluid with visible or settling particles, often needing shaking.

Physical character

particle size: large enough to settle and be filtered note

behaviour: settles over time note

registry parent: dispersion note

How it is recognised

Heterogeneous mixture of settling particles in fluid

Slurry ice, cell suspension, milk of lime, electrorheological fluid, Zagy, Moonmilk

Solutions are homogeneous; colloids have tiny non-settling particles; emulsions disperse liquids; other senses of suspension are unrelated
